you shouldn't have guns around your son. that is very possible. >> someone wants to go in and buy a firearm, there could be a law that they have to go in and get mentally checked out. >> i could see that people will be disturbed and i could see it would be very difficult to pull off. what i think is probably more practical, if you will, is if people understood the signs and symptoms of mental illness, basically any emotional state, and brought them in to get treatment, to enter the system, those that would be dangerous would be dealt with appropriately. those who maybe don't appear dangerous, but shouldn't have a firearm would be told so. and their families would be told so. because, of course, in this case, he didn't buy the guns. his mother did. >> but you also run into the issue of seeing a doctor, having it covered, insurance issues, it's one domino after another.
